General Description

The CDK1303 is a full parallel (flash) analog-to-digital converter capable

of digitizing full scale (0 to -2V) inputs into eight-bit digital words at an

update rate of 1 GSPS. The ECL-compatible outputs are demultiplexed into

two separate output banks, each with differential data ready outputs to ease

the task of data capture. The CDK1303’s wide input bandwidth and low

capacitance eliminate the need for external track-and-hold amplifiers for most

applications. A proprietary decoding scheme reduces metastable errors to the

1 LSB level. The CDK1303 operates from a single -5.2V supply, with a nominal

power dissipation of 5.5W.

The CDK1303 is available in an 80-lead surface-mount MQUAD package over

the industrial temperature range (-25°C to +85°C).
